| Abstract: | Solid acids such as Cs_ n H_ 3- n PW_ 12 O_ 40 (Cs_ n PW_ 12 ) and SO 2- _4/ZrO_2 were used to catalyze the esteritication of n -hexanol. The effects of the cesium contents and acid intensity of Cs_ n PW_ 12 and the conentration of the impregneted sulphuric acid and acid intensity of SO 2- _4/ZrO_2, as well as different organic acids on the topical reaction were investigated. The results showed that their catalytic activity could be improved with the increase of acid intensity and specific surface area. The catalysts were characterized by IR, XRD and air adsorption. |
